Cagan, Los Angeles, Alfred E. Ziroli, Manhattan Beach, and Paul Harestad, Torrance, Calif., assignors to Eldon Industries, Inc., Los Angeles, Calif., a corporation of California Filed May 18, 1960, Ser. No. 29,943 1 Claim. (Cl. 259-177) This invention relates to toys and is particularly directed to a novel form of cement mixer truck having a rotary mixer drum in the form of a sand pail.

The principal object of this invention is to provide a toy truck simulating a cement mixer truck having a rotary drum, the dnnn being detachable for use as a sand pail and being mounted on a tilt frame for a rotary movement to simulate the rotary movement of a mixer drum.

Another object is to provide a device of this type in which gearing is used for rotating the mixer drum, which gearing permits separation of parts thereof when the drum is detached for use as a sand pail.

Another object is to provide a device of this type particularly adapted for construction from polyethylene plastic material.

A further object is to provide a device particularly suited for manufacture on a quantity production basis.

Other and more detailed objects and advantages will appear hereinafter.

In the drawings:

FIGURE 1 is a side elevation showing a preferred form of our invention.

FIGURE 2 is a side elevation partly broken away and showing the tilt frame and rotary member in dumping position.

FIGURE 3 is a View taken substantially in the direction of the line 3-3 as shown in FIGURE 2..

FIGURE 4 is a sectional elevation taken substantially on the lines 44 as shown in FIGURE 2.

FIGURE 5 is a sectional detail taken substantially on the lines 5-5 as shown in FIGURE 3.

FIGURE 6 is a sectional detail taken substantially on the lines 6-6 as shown in FIGURE 2, and showing in phantom lines the rotary member in detached position.

FIGURE 7 is a sectional detail taken substantially on the lines 77 as shown in FIGURE 1.

Referring to the drawings, the toy truck generally designated 10 is provided with a truck bed 11 supported on wheels 12. The wheels are mounted on axles 13' and 14 which are fastened to tabs 15 projecting downwardly from the bed '11.

A tilt frame 16 is mounted for pivotal movement on the truck bed 11. Aligned pivot pins 17 carried on upwardly directed ears 18 extend through apertures provided in bosses 19 on the tilt frame 16. FIGURE 1 shows the tilt frame 16 in lower position and FIGURE 2 shows it in upper position.

As best shown in FIGURE 7 the tilt frame 16 is provided with wing sections 19 cooperating to define an arcuate surface 20 for slidably contacting the outer surface 2 1 of the tapered wall 22. of the rotary member 25. This rotary member is shaped in the form of a sand pail having an open upper end 26 and having a bottom wall 27. A bail 28 is pivotally attached at 29 at diametrically opposite points to the rotary member 25 adjacent the open end 26. p

The tilt frame 16 has an upstanding central bracket 31 having an end surface 32. An aperture 36 is formed in this end surface and a central plug 3 4 on the bottom "ice wall 27 of the rotary member 25 extends through this aperture. The plug 34 is formed of resilient material and is provided with a peripheral skirt 35'. This skirt 35 acts resiliently to prevent separation of the flange 3-2 and bottom wall 27 of the rotary member 25 However, under endwise load the skirt 35 deforms sufiiciently to permit separation of the parts so that the member 25 can be disconnected from the tilt frame 16 and other parts of the toy truck 10, and used separately as a sand pail.

Means is provided for rotating the member 25 while it is in position on the tilt bed 16, and as shown in the drawings, this means includes a shaft 40 rotatably mounted on the part 31 of the tilt frame 16. A pinion gear 42 is fixed on the shaft 40 and meshes with the teeth of a ring gear 43 provided on the lower face of the bot tom 27 of the member 25. A manually operable crank 45 is provided for rotating the pinion gear 42 and thereby turning the ring gear 43 and rotary member 25. When the bail 28 is swung to operating position and used to apply endwise force to the member 25- the plug 34 is withdrawn through the aperture 33 and the ring gear 43 moves out of meshing engagement with the pinion 4 2. The member 25 may then be lifted upward away from the arcuate surface 22 defined by the wing sections 19 on the tilt bed 16. Reassembly of the member 25 with respect to the tilt bed 16 is accomplished by resting a member 25 in the position shown in FIGURE 1 and then applying endwise force to the center portion of the bottom wall 27 to force the plug 34 through the aperture 33-.

The angle of inclination of the rotary member 25 on the tilt bed 16, as shown in FIGURE 1, is sufiiciently great to retain sand or other material inside the member 25 when it is turned by means of the crank 45. Such material may be discharged from tne interior of the member 25 by swinging the tilt frame 16 to the dumping position shown in FIGURE 2.

Having fully described my invention it is to be understood that we do not wish to be limited to the details set forth above, but our invention is of the full scope of the appended claim.

We claim:

In a toy cement mixer truck a combination of: a toy truck bed having supporting wheels, a tilt-frame privotally mounted on the said truck bed, a pail-shaped rotary member having an open end and having a bottom wall remote therefrom and having a tapered side wall, means for removably mounting said rotary member for rotary movement upon said tilt-frame, said means including a U-shaped support element on the tilt-frame slidably engaging said side wall of said rotary member, said means also including a central axial projection on said bottom wall engaging an element on said flit-frame, resilient means resisting axial separation of said projection and said element, a ring gear on said bottom wall of the rotary member, a pinion gear rotatably supported upon said tilt-frame and meshing with said ring gear, means for turning said pinion gear, and a bail pivoted to said rotary member nearest the open end thereof for overcoming said resisting means and facilitating manual removal of said rotary member from said tilt-frame.
